A Microfluidic Brain Interface for In Vivo Recording of Neurochemical Activity

Guillaume Cédric Yves Petitpierre

Neurological disorders have a strong negative impact on the quality of life of affected patients, their close relatives as well as on the health economic system. Early diagnosis associated with better treatment outcomes remain difficult to reach. Similarly ...

Mapping the function of neuronal ion channels in model and experiment

Rajnish Ranjan, Alexander Kevin Seeholzer, Tim Vogels, William Francis Podlaski

Ion channel models are the building blocks of computational neuron models. Their biological fidelity is therefore crucial for the interpretation of simulations. However, the number of published models, and the lack of standardization, make the comparison o ...

Improved hybrid/GPU algorithm for solving cardiac electrophysiology problems on Purkinje networks

Alfio Quarteroni, Christian Vergara, Toni Mikael Lassila

Cardiac Purkinje fibers provide an important pathway to the coordinated contraction of the heart. We present a numerical algorithm for the solution of electrophysiology problems across the Purkinje network that is efficient enough to be used in in silico s ...

Cortical afferents onto the nucleus Reticularis thalami promote plasticity of low-threshold excitability through GluN2C-NMDARs

Gil Vantomme, Simone Astori

Thalamus and cortex represent a highly integrated processing unit that elaborates sensory representations. Interposed between cortex and thalamus, the nucleus Reticularis thalami (nRt) receives strong cortical glutamatergic input and mediates top-down inhi ...

On the role of water density fluctuations in the inhibition of a proton channel

Lucie Monique Françoise Delemotte

Hv1 is a transmembrane four-helix bundle that transports protons in a voltage-controlled manner. Its crucial role in many pathological conditions, including cancer and ischemic brain damage, makes Hv1 a promising drug target. Starting from the recently sol ...

Sodium Signaling and Astrocyte Energy Metabolism

Pierre Magistretti, Jean-Yves Chatton

The Na+ gradient across the plasma membrane is constantly exploited by astrocytes as a secondary energy source to regulate the intracellular and extracellular milieu, and discard waste products. One of the most prominent roles of astrocytes in the brain is ...

Intercellular ultrafast Ca2+ wave in vascular smooth muscle cells: numerical and experimental study

Jean-Jacques Meister, Niccolo Piacentini, Jairo Camilo Quijano Perez, Franck Claude Raynaud

Vascular smooth muscle cells exhibit intercellular Ca2+ waves in response to local mechanical or KCl stimulation. Recently, a new type of intercellular Ca2+ wave was observed in vitro in a linear arrangement of smooth muscle cells. The intercellular wave w ...

RIM1 and RIM2 redundantly determine Ca2+ channel density and readily releasable pool size at a large hindbrain synapse

Ralf Schneggenburger, Yunyun Han, Zsolt Norbert Babai

The localization and density of voltage-gated Ca2+ channels at active zones are essential for the amount and kinetics of transmitter release at synapses. RIM proteins are scaffolding proteins at the active zone that bind to several other presynaptic protei ...

Motor Control in the Mouse Whisker System

Varun Sreenivasan

The motor systems of the mammalian brain are a remarkable product of many millions of years of evolution. It is the motor systems that make us and other mammals mobile, that guide our actions in response to sensory information and conversely modulate the v ...
